Normalized pulse profiles of NGC 300 ULX1. Subplots correspond to different epochs (see Table B.1) and are sorted in decreasing spin period (from top to bottom panels). Pulse profiles derived by Chandra (panels a and e) contain events with energies in the 0.3–8.0 keV band, while those derived from XMM-Newton data (panel c) and Swift (panels b and d) denote the 0.3–10.0 keV range.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
